• *1: Exemplary calculation of print speed: If 28 ppm can be achieved at a print productivity of 100 % on A4 plain paper, a change in print
productivity to 90% results in 25.2 ppm.
• *2: Execution of the control for the high humidity environment mode can be prohibited by turning ON "No. 5 PPM control (high humidity
environment mode) prohibited" of Engine FW DIP switch of Enhanced Security of the service mode.
• *3: For recycled paper, the print productivity will be set to 70% when "Mode 3" is selected for warm-up choice.
(6) Fusing unit detection
(a) Unit mounting detection
• The machine detects the mounting condition of the fusing unit.
• When fusing unit is detected in the mounted condition, the machine begins the initial operation.
Detection timing
• The unit mounting detection control is performed under any of the following conditions:
"The power switch is turned ON (with the front door and right door are closed)"
"The machine exits the sleep mode"
"The front door or right door is opened and closed with the power switch in ON position"
Operation when it is detected that no units are mounted
• The message "Fusing Unit Installation Error" appears on the operation panel, and the machine prohibits initial operation and any new
print cycle.
The message "Fusing Unit Installation Error" disappears as soon as a fusing unit is mounted.
(b) Fusing unit new article detection
• The fusing unit is not provided with any new article detection mechanism. If the fusing unit is replaced with a new one, therefore, "New
Release" of "Fusing Unit" must be performed in "Counter/ Life" of the service mode.
